RMariaDB 1.3.0 (2023-10-08)
Features
- Connections now inherit from
"MySQLConnection"if a MySQL server is detected (server version < 10.0 or server description contains"MariaDB"). The newmysqlargument todbConnect()allows overriding the autodetection (#303). - Use string as default for JSON (#296) and all unknown column types (@LeeMendelowitz, #260).

TIMEcolumns with subsecond precision (@renkun-ken, #288, #289).
Chore
- Update Windows libs to new location (#301).

RMariaDB 1.2.2 (2022-06-19)
Features
dbAppendTable()acceptsId(#262, @renkun-ken).dbConnect()gainsreconnectargument that sets theMYSQL_OPT_RECONNECToption (#261, @renkun-ken).
RMariaDB 1.2.1 (2021-12-20)
Internal
- Make method definition more similar to S3. All
setMethod()calls refer to top-level functions (#250).
RMariaDB 1.2.0 (2021-12-12)
Features
- BLOBs are returned as
blob::blob()objects (#126, #243). -
dbWriteTable()anddbAppendTable()are much faster thanks toLOAD DATA LOCAL INFILE. To activate this,load_data_local_infile = TRUEmust be passed todbConnect(). The readr package is required (#11, #223).
RMariaDB 1.1.2 (2021-09-06)
Licensing
- RMariaDB is now licensed under the MIT license (#213).
Features
-
dbConnect()normalizes all input paths (#197, @twentytitus). -
dbDataType()returnsTIME(6)fordifftime, andDATETIME(6)forPOSIXtcolumns, to create columns with microsecond precision by default (#214).
Documentation
- Now referring to the
libmariadb-devDebian/Ubuntu package in documentation and configuration scripts (#219). -
?dbConnectgains a section on secure passwords and the.mylogin.cnffile (#156).
RMariaDB 1.1.1 (2021-04-12)
Bug fixes
-
NULLis mapped toNAforbit(1)columns (#201, @dirkschumacher).
Internal
- Remove BH dependency by inlining the header files (#208).
RMariaDB 1.1.0 (2021-01-05)
Features
-
dbConnect()now supports atimezone_outargument. Explicitly settingtimezonetoNULLtries to detect the database time zone (#116). -
BIT(1)columns are returned aslogical(#84). -
dbQuoteLiteral()now correctly quotes difftime values (#188).
Bug fixes
- Timestamp values are now written correctly if the database connection uses a time zone other than UTC. Deviations still might occur at DST boundaries, therefore it is still safer to use UTC as the database connection (#116).
- Timestamp roundtrip no longer fails on Windows i386 (#117).
-
dbBind()also works for"Date"values that are stored as integers (#187).
RMariaDB 1.0.11 (2020-12-16)
Features
- Windows: update to libmariadbclient 3.1.11
- Add
timezoneargument todbConnect()(#184, @ycphs). -
dbWriteTable()anddbBind()correctly interpret difftime values with units other than"secs".
RMariaDB 1.0.10 (2020-08-26)
Features
-
dbConnect()gains atimeoutargument, defaults to 10. UseInfor a negative value for no timeout (#169). - Support fractional seconds in datetime values for reading and writing (#157).
Bug fixes
-
dbDataType()returnsVARCHAR(1)for length-0 character vectors. -
dbDataType()returnsVARCHAR()for factors. -
dbSendQuery()anddbSendStatement()clear the result set ifdbBind()throws an error. - Check that input to
dbWriteTable()is a data frame (#160, @rossholmberg).
RMariaDB 1.0.8 (2019-12-17)
- Implement
dbGetInfo()according to the specification. - Include information about
libssl-devinconfigureandDESCRIPTION(#101).
RMariaDB 1.0.6 (2018-05-05)
- Add support for
bigintargument todbConnect(), supported values are"integer64","integer","numeric"and"character". Large integers are returned as values of that type (r-dbi/DBItest#133). - Data frames resulting from a query always have unique non-empty column names (r-dbi/DBItest#137).
- New arguments
temporaryandfail_if_missing(default:TRUE) todbRemoveTable()(r-dbi/DBI#141, r-dbi/DBI#197). - Using
dbCreateTable()anddbAppendTable()internally (r-dbi/DBI#74). - Implement
format()method forMariaDBConnection(r-dbi/DBI#163). - Reexporting
Id(),DBI::dbIsReadOnly()andDBI::dbCanConnect(). - Now imports DBI 1.0.0.
RMariaDB 1.0.5 (2018-04-02)
-
dbGetException()is no longer reexported from DBI. -
NaNandInfare converted toNULLwhen writing to the database (#77). - Values of class
"integer64"are now supported fordbWriteTable()anddbBind()(#87). - Schema support, as specified by DBI:
dbListObjects(),dbUnquoteIdentifier()andId(). - Names in the
xargument todbQuoteIdentifier()are preserved in the output (r-lib/DBI#173). - Replace non-portable
timegm()with private implementation (#78). - Update libmariadbclient to version 2.3.5 on Windows (#92, @jeroen).
RMariaDB 1.0-4 (2017-12-11)
- Attempt to fix Solaris builds by redefining
timegmsymbol if the macrosunis defined. - Fix examples running on CRAN by using only temporary tables and
overwrite = TRUE. - Refactor connection and result handling to be more similar to other backends.
- Add support for R 3.1, but DBI >= 0.5 is required (#68).
- Queries that bypass the prepared statement framework (like
SHOW PLUGINS) return data (#70, @nbenn). - A temporary table can be created via
dbWriteTable()if a table by the same name exists. If a temporary table of the same name exists, the error will be raised by the database itself, because this condition cannot be checked beforehand.
RMariaDB 1.0-2 (2017-10-01)
Initial release, compliant to the DBI specification.
- Test almost all test cases of the DBI specification.
- Fully support parametrized queries (#22, #27, #39).
- Queries not supported by the prepared statement protocol still can be run via
dbExecute()ordbSendStatement(), the functionmariadbExecQuery()has been removed (#28). - Spec-compliant transactions (#38, #49).
- 64-bit integers are now supported through the
bit64package. Unfortunately, this also means that numeric literals (as inSELECT 1) are returned as 64-bit integers (#12). - Correct handling of DATETIME and TIME columns (#52, @noahwilliamsson). Support timestamp values with sub-second precision on output, and with year beyond 2038 (#56).
- The connection now uses the “utf8mb4” charset by default (#7).
- New default
row.names = FALSE. - New SSL-related arguments to
dbConnect():ssl.key,ssl.cert,ssl.ca,ssl.capath,ssl.cipher(#131, #148, @adamchainz). - CI for Linux, Windows, and OS X (#25).
- Support for Connector/C from both MariaDB and MySQL.
RMariaDB 0.11-1 (2016-03-24)
RMariaDB fully supports DATE and DATETIME columns. On output, DATE columns will be converted to vectors of
Dates and DATETIME will be converted toPOSIXct. To faciliate correct computation of time zone, RMariaDB always sets the session timezone to UTC.RMariaDB has been rewritten (essentially from scratch) in C++ with Rcpp. This has considerably reduced the amount of code, and allow us to take advantage of the more sophisticated memory management tools available in Rcpp. This rewrite should yield some minor performance improvements, but most importantly protect against memory leaks and crashes. It also provides a better base for future development.
Support for prepared queries: create prepared query with
dbSendQuery()and bind values withdbBind().dbSendQuery()anddbGetQuery()also support inline parameterised queries, likedbGetQuery(mariadbDefault(), "SELECT * FROM mtcars WHERE cyl = :cyl", params = list(cyl = 4)). This has no performance benefits but protects you from SQL injection attacks.dbListFields()has been removed. Please usedbColumnInfo()instead.dbGetInfo()has been removed. Please use the individual metadata functions.Information formerly contain in
summary()methods has now been integrated intoshow()methods.make.db.names()has been deprecated. UsedbQuoteIdentifier()instead.isIdCurrent()has been deprecated. UsedbIsValid()instead.dbApply(),dbMoreResults()anddbNextResults()have been removed. These were always flagged as experimental, and now the experiment is over.dbEscapeStrings()has been deprecated. Please usedbQuoteStrings()instead.dbObjectId compatibility shim removed
Add SSL support on Windows.
Fix repetition of strings in subsequent rows (@peternowee, #125).
Always set connection character set to utf-8
Backport build system improvements from stable branch
Reenable Travis-CI, switch to R Travis, collect coverage
